Two siphon chambers 237 of the detergent box 230 are arranged corresponding to the feeding port 2121, namely a detergent siphon chamber 2371 and a softener siphon chamber 2372. Two water inlets 233 are correspondingly arranged and are respectively communicated with a detergent siphon cavity 2371 and a softener siphon cavity 2372. The box 210 is substantially rectangular, the inlet 2121 is preferably a circular inlet 2121, and the detergent box 230 has a detergent siphon chamber 2371 on one side in the longitudinal direction and a softener siphon chamber 2372 on the other side. Because the amount of detergent required during the washing process is generally greater than the amount of softener, a detergent siphon chamber 2371 is provided with a volume greater than that of softener siphon chamber 2372, and detergent siphon chamber 2371 and softener siphon chamber 2372 are separated by partition 236. The water inlet 233 of both the detergent siphon chamber 2371 and the softener siphon chamber 2372 are provided with a drain passage. Siphon component 2373 in detergent siphon chamber 2371 and softener siphon chamber 2372 sets up in one side of input 2121, prevents to throw into detergent and softener time, directly pours into on siphon component 2373, influences solvent mixture and siphon effect.

According to the water inlet box assembly, the siphon cavity 2371 and the siphon part 2373 are arranged in the detergent box 230, so that water and detergent entering the detergent box 230 are fully mixed and then flow into the water outlet 214 at the bottom of the box body through the siphon part 2373 to flow out, meanwhile, the siphon part 2373 can ensure that a certain amount of water flows out of the water outlet, and the water outlet can ensure that the water flows out uniformly; if the strip-shaped water outlets are arranged, the uniformly sprayed water flow has a washing effect on the clothes, and dirt on the clothes can be removed conveniently.

The water inlet 233 of the detergent box 230 communicates with a water inlet passage and a drain passage. A part of water flowing out of the water inlet 233 flows into the siphon chamber 237 through the water inlet channel, flows into the accommodating chamber of the box body 210 after being mixed with detergent and the like, and flows out of the water outlet 214 to the inner drum of the washing machine; and another portion of the water flow exits the cartridge 210 through the drain passage. By arranging the drainage channel at the water inlet 233 of the detergent box 230, when water is fed, part of the water directly flows out of the box body 210 through drainage and does not enter the siphon cavity 237, so that excessive water flow is prevented from entering the siphon cavity 237, the water level in the siphon cavity 237 is prevented from being excessively high, water overflows, and water and detergent overflow from the box body 210; and the structure of the drainage channel is simple, and the manufacturing cost is low.

In order to sufficiently mix the detergent and the like in the detergent box 230 with water and dissolve and flush out all the detergent, a water diversion plate 220 is further provided above the siphon chamber 237 in the detergent box 230. As shown in fig. 6, the water diversion plate 220 is provided with a plurality of water leakage holes, which are uniformly distributed above the siphon cavity 237. A part of the water flowing out of the water inlet 233 flows into the upper side of the water diversion plate 220 through the water inlet passage, and then flows into the siphon chamber 237 through the water leakage holes of the water diversion plate 220. In this embodiment, water diversion plate 220 includes first water diversion plate 221 and second water diversion plate 222, and first water diversion plate 221 is disposed on an upper side of detergent siphon cavity 2371, and second water diversion plate 222 is disposed on an upper side of softener siphon cavity 2372.

The water inlet 233 is located near the upper side of the detergent box 230 and the bottom plate is located higher than the detergent box 230, so that the water inlet cavity is located at a high position, which facilitates the water flow to enter the water diversion plate 220 and ensures the water amount to enter the siphon cavity 237. The bottom of the water inlet cavity is provided with a drainage channel which is communicated with the accommodating cavity of the box body 210, and water flowing out of the drainage channel flows into the accommodating cavity of the box body 210 below and is discharged from the water outlet 214. The water discharged from the siphon may be mixed with the water discharged from the siphon, so that the detergent and the water are further uniformly mixed and flow out of the water outlet 214. In other embodiments, the drainage channel may also be directly connected to the outside of the box 210, for example, a water outlet hole for draining the drainage water is additionally disposed on the box 210, so that the drainage water does not pass through the accommodating cavity of the box 210 and the water outlet 214, and the drainage water can be drained from the box 210 more quickly.

Specifically, as shown in fig. 8, a drain hole 234 is formed in the bottom of the water inlet cavity, i.e., the bottom plate, and the drain hole 234 communicates with the accommodating cavity of the cartridge body 210 and the water outlet 214 to form a drain channel. In this embodiment, two drain holes 234 are formed in the detergent siphon chamber 2371 at the water inlet 233, and are located on the left and right sides of the water inlet 233, respectively, according to the amount of water to be drained.

A drain chamber 238 is disposed adjacent to the siphon chamber 237, and the drain chamber 238 is used to drain water overflowing the siphon chamber 237 out of the cartridge body 210. When the water inflow is too large, after a part of the water is discharged from the drainage channel at the water inlet 233, a large amount of water still enters the siphon cavity 237, so that the water in the siphon cavity 237 is too large, and at this time, the water overflowing from the siphon cavity 237 can be discharged out of the box body 210 from the drainage cavity 238 through the drainage cavity 238, so as to prevent the water from overflowing from the top of the box body 210.

In the present embodiment, a stopper rib 239 is provided at the bottom inside detergent box 230, and the stopper rib 239 divides the inner area of detergent box 230 into a siphon chamber 237 and a drain chamber 238. The rib 239 and the inner sidewall of the detergent box 230 form a drain chamber 238. An opening 2386 is formed at the bottom of the drainage cavity 238, and the drainage cavity 238 is communicated with the accommodating cavity of the box body 210 and the water outlet 214 through the opening 2386. The water flowing out of the drainage chamber 238 flows into the receiving chamber of the lower cartridge 210 and is discharged through the outlet 214. The water from the drainage chamber 238 can be mixed with the water from the drainage channel and the siphoned water to further mix the detergent and water uniformly and flow out of the water outlet 214. In other embodiments, the drainage lumen 238 may be in direct communication with the exterior of the cartridge 210, and not pass through the receiving lumen of the cartridge 210 and the outlet 214, allowing the overflow water to exit the cartridge 210 more quickly.

The number of the bleed flow chambers 238 may be plural, and the volume of the chamber may be different. By providing multiple segments of ribs 239, a plurality of drainage lumens 238 are formed. It is understood that the height of the rib 239 is lower than the height of the wall 235 of the detergent box 230 and the wall of the water outlet 214. In this embodiment, two drain chambers, a first drain chamber 2381 and a second drain chamber 2382, are provided in the detergent siphon chamber 2371. The rib 239 includes a first rib 2391 and a second rib 2392, and the first rib 2391 and the second rib 2392 are both L-shaped ribs 239. The first blocking rib 2391 is arranged close to one side wall of the detergent box 230, one end of the first blocking rib is connected with the front side wall of the detergent box 230, the other end of the first blocking rib is connected with the surrounding wall 235 at the water inlet 233, and an L-shaped first drainage cavity 2381 is formed between the first blocking rib 2391 and the side wall of the detergent box 230. One end of the second rib 2392 is connected to the other side wall 235 of the water inlet 233, and the other end is connected to the rear side wall of the detergent box 230, forming a rectangular second drainage chamber 2382. Softener siphon chamber 2372 includes three drainage chambers, three segments of blocking ribs. The rib 239 includes a third rib 2393, a fourth rib 2394, and a fifth rib 2395. A third rib 2393 is arranged near the side wall of the detergent box 230, one end of the third rib 2393 is connected with the front side wall of the detergent box 230, and the other end is connected with the rear side wall of the detergent box 230. A third leakage cavity 2383 is formed between the third rib 2393 and the inner wall of the detergent box 230. One end of the fourth rib 2394 is connected to one side of the surrounding wall 235 at the water inlet 233, and the other end is connected to the middle partition 236, forming a fourth drainage chamber 2384 with the rear side wall of the detergent box 230. The fifth barrier rib 2395 is L-shaped, one end of which is connected to the other side of the surrounding wall 235 at the water inlet 233 and the other end of which is connected to the rear side wall of the detergent box 230, forming a fifth relief chamber 2385. Because the water quantity of the detergent siphon cavity is larger than that of the softener siphon cavity, a larger drainage cavity is arranged in the detergent siphon cavity. Meanwhile, in order to increase the drainage speed of the first drainage cavity 2381 at the side of the detergent siphon cavity, the bottom of the detergent box at the detergent siphon cavity is obliquely arranged and is obliquely and downwards arranged from the outer side to the inner side, so that the space at one side between the outer bottom surface of the detergent box and the inner bottom surface of the box body is larger, and the drainage function of the first drainage cavity 2381 is increased.

In other embodiments, the number, location, and size of the drain cavities 238 are not particularly limited.

In this embodiment, the rib 239, the partition 236 and the detergent box 230 are integrally formed, the detergent box 230 includes a detergent box cover 231 and a detergent box 232, and the detergent box cover 231, the detergent box 232 and the partition 236 are connected by welding to prevent water from overflowing from the upper side.

In order to further improve the drainage effect, the drainage cavity 238 is located below the water diversion plate 220, a part of water flowing out from the water leakage hole of the water diversion plate 220 directly flows into the drainage cavity 238 and does not enter the siphon cavity 237, i.e. a part of water flowing down from the water diversion plate 220 enters the siphon cavity 237 and a part of water flows into the drainage cavity 238, as shown by the arrow in fig. 10, the water flows in the direction shown by the arrow, when the water amount is too high, the water can firstly pass through the drainage cavity 238 to drain, and finally, if the water level in the siphon cavity 237 is still too high and exceeds the rib 239, the water overflows into the drainage cavity 238 to drain. At this point, the bleed chamber 238 serves a dual bleed function to ensure that the water level in the siphon chamber 237 is normal.

The inner wall of the circumference of the detergent box 230 is inclined toward the inside of the detergent box 230. The water flowing into the drainage chamber 238 from the water diversion plate 220 can be collected into the receiving chamber of the box body 210 below along the inner wall of the inclined detergent box 230, and the inner wall of the inclined detergent box 230 can play a role of diversion, so that the overflowed water is collected towards the middle of the box body 210 and flows towards the water outlet 214 in the middle of the box body 210. In this embodiment, as shown in fig. 12, the water outlet 214 is elongated, and the water flowing out fills the water outlet 214 and flows out in a strip shape, so as to form a water flow having a width of the water outlet 214, such that the width of the water flow is large, the spraying range after being sprayed to the inner tub of the washing machine is large, contact between the clothes in the washing machine and the sprayed water flow is increased, the sprayed water flow forms a washing effect on the clothes, and removal of dirt on the clothes is facilitated. In other embodiments, the water outlet 214 may be one or more rows of water outlet holes.

As shown in fig. 11, at least one water blocking rib 216 is disposed on the box body 210 at the bottom of the accommodating chamber, and water siphoned out by the detergent box 230 is guided to the water outlet 214 through the water blocking rib 216. Through the water conservancy diversion effect of manger plate muscle 216, can make rivers flow to delivery port 214 more fast, and when siphon rivers were too big, can play and block the water conservancy diversion effect, prevent that rivers are partial to one side, influence the play water effect of delivery port 214, make the velocity of flow on the delivery port 214 bar width the same with the flow or close, guarantee that it is even to go out water.

When the water amount is too large and the water leaks from the drainage cavity 238, the water blocking rib 216 can guide the water flowing out from the drainage cavity 238, so as to prevent the water flowing out from the drainage cavity 238 from flowing over a large area, which causes the water flow to be deviated to one side.

The water blocking rib 216 is obliquely arranged on the bottom surface of the box body 210, one end of the water blocking rib 216 close to the water outlet 214 is arranged close to the central line of the water outlet 214, and the other end far away from the water outlet 214 is arranged far away from the central line of the water outlet 214. That is, from the water outlet 214, the water blocking ribs 216 are radially distributed, so that the water flow on the rear side and the water flow on the two sides can be guided and converged to the middle water outlet 214. In the embodiment, the drainage cavities 238 are disposed at both sides and the rear side of the detergent box 230, and the water blocking ribs 216 can well guide and collect drainage water flow at the rear side and both sides to the middle water outlet 214.

The water outlet 214 is disposed along the length of the cartridge body 210 and near the front side wall of the cartridge body 210. The water blocking ribs 216 are arranged on the rear side, and the water blocking ribs 216 can better play a role in guiding water flow on the two sides and the rear side.

In this embodiment, since the amount of water in the detergent siphon chamber 2371 is large, it is preferable that four water-blocking ribs 216 are provided, including a first water-blocking rib 2161, a second water-blocking rib 2162, a third water-blocking rib 2163, and a fourth water-blocking rib 2164. The water blocking rib 216 under the detergent siphon chamber 2371 and located at the outer side, i.e. the water blocking rib 216 close to the first drainage chamber is a first water blocking rib 2161, which is arc-shaped, and the front end of the first water blocking rib 2161, i.e. the end close to the water outlet 214, is bent outward, i.e. slightly bent toward the first drainage chamber.
